CORNER-BAR.

Specication of Letters Patent. Application filed .T uly 29, 1912. SerialNo. 712,023.

Patented July 1 1913.

To all 'whom t may concern.'

Be it known that I, HUGH J. FIXMER, a

citizen of the United States, residing at Edison Park, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Corner-Bars, of

`which the following is a specification.

'vide a simple andcheap bar of the kind stated which will presentadurable surface where the wearlis greatest, or shocks mostfrequent, andeectually prevent damage.

The invention also has for its object .to provide simple and improvedmeans for anchoring the bar in the concrete or other plastic material.

In the accompanying drawing forming a part of this specification, Figure1 is a perspective view of the corner bar constructed in .accordancewith theinvention, and Figs. 2 to 5 show diferent applications thereof.Fig. 6 shows a modified form of bar.

Referring specificallyl to the drawing, the corner bar is a metal stripwhich is angular in cross-section to form two wings 5 and 6 which arearranged at right angles toone another. A plain angle bar of uniformthickness is preferably employed, but if desired, a 'bar may be employedwhich is tapered toward one of its longitudinal edges as shown in Fig.6. Within the .angle formed by the wings are anchoring tongues 7 whichare vformed by making transverse slits in the wing 6, said slitsextending from the edge thereof and terminating at the an le. The slitsare in pairs, and the materlal between each pair is bent downward toform a tongue. It will be noted that the. slits of each pair converge inthe direction of the angle, in view of which the tongue is given agreater width at its extremity than at its base. By the dove-'tail shapeof the tongue, it is firmly embedded in the concrete or other plasticmaterial, and the bar will bel securely anchored therein.

Fig; 2 shows the bar applied to a curb, the bar, by reason of itsangular cross-section, covering the corner, and thereby proteeting thesame from damage. The bar is embedded in the concrete or other plasticmaterial of which the curb is formed, iush therewith. The ton es 7 arealso embedded in the materlal and thus serve to firmly anchor the bar.

Fig. 3 shows the bar applied to concrete pavement expansion joints. Thewings 5 are at the top and are showngrooved to prevent slipping.

Fig. 4 shows the bars applied to stair or step treads, and in Fig. 5 isshown a column, door jamb or similar structure having its cornersprotected by the bars.

The bars can be bent to-any curve on the job, they can be easily andcheaply produced, and they eectually serve the purpos for which they aredesigned. o,

I claim:

-A corner bar which is angular in crosssection to form two wingsarranged at an angle to one another, one of said wings having slitsextending from its edge and terminating at the angle, said slits beingin pairs, the members o-f said pairs of slits converging in thedirection of the angle, and the material between said pairs being bentto form tongues which project from the inner angle of the bar.

A In testimony whereof I affix my signature in presence of twowitnesses.
